TAS5754M basic register configuration

Other Parts Discussed in Thread: TAS5754M

Is there a basic (configures the least number of registers) HybridFlow configuration available for the

1)      1) TAS5754M using HybridFlow 4 for a mono subwoofer and

2)      2) TAS5754M using HybridFlow 1 for a stereo L + R speaker

 

PurePath Console GUI develops a base configuration .cfg file for all the registers in the TAS5754M. I would like to configure the least number of registers possible by using as many as possible default (from Power-on-Reset) register settings for 1) a subwoofer and 2) a stereo L + R speaker.

 

I have one processor using I2C to configure both the subwoofer TAS5754M amp and the Stereo L + R Speaker TAS5754M amp and have minimal memory available on the MCU.

    Hi Rob,

    The current process requires you to do a register dump at start with defaults and another after downloading HF settings. Then doing a comparison to see what registers are change and writing  only those registers. We will be releasing new version of the GUI next month that will do this for you. It allows you to take snapshots and it will generate a dump of the differences.

    We thought of this already — the problem is that once you use any EQ at all, about 75% of the registers are affected (different than the default values).  So we still need to write around 3,000 registers.

     

    Any other insights would be really valuable.
